Abstract
Description
Technical Field
[0001] The present application relates to the field of intelligent cleaning technology, and in particular, to a base station and system of a wiping robot. Background Art
[0002] A wiping robot system is a type of smart home appliance, typically consisting of a wiping robot and a base station. The wiping robot uses suction generated by a vacuum source to firmly adhere to the surface being wiped and cleans the surface using a cleaning cloth at its base. The base station is equipped with a storage slot for accommodating the wiping robot when not wiping. The base station is also equipped with a safety rope that connects to the wiping robot. If the wiping robot falls, the base station can apply force to the robot through the safety rope to prevent it from hitting the ground and causing danger.
[0003] Chinese utility model patent CN220655475U discloses a cleaning system and base station, comprising a base and a flip cover. The base defines a storage cavity with an opening. The flip cover is hinged to the base at one end and detachably connected to the base at the other end via a locking assembly. When the flip cover is connected to the base, it at least partially covers the opening. However, the utility model patent does not disclose how the base station is secured to the ground.
[0004] Chinese utility model patent CN218165108U discloses a fixed structure, a storage box device and a cleaning machine assembly, wherein the fixed structure includes: an adsorption element, a sealed cavity is formed in the adsorption element; and a pressure relief structure connected to the adsorption element, which is used to adjust the vacuum degree in the sealed cavity. When the storage box device needs to be used, the through hole is closed by a switch, and the negative pressure structure extracts the air in the sealed cavity, thereby increasing the vacuum degree in the sealed cavity. At this time, the sealed cavity in the adsorption element is isolated from the outside air, and the adsorption element can be adsorbed on the surface of an object or the ground by its own weight. Furthermore, the degree of opening and closing of the through hole can be controlled by a switch through rotation, pressing, remote control, mobile phone APP, etc., thereby controlling the vacuum degree in the sealed cavity. In this way, the utility model patent discloses that the base station is adsorbed on the surface of an object or the ground through a suction cup, so that a force can be applied to the wiping robot through a safety rope to prevent the wiping robot from falling to the ground and causing danger.
[0005] According to Chinese utility model patent CN220655475U, the base station is provided with a storage cavity and a flip cover for closing the storage cavity. According to Chinese utility model patent CN218165108U, the base station is provided with an adsorption element and a pressure relief element connected to the adsorption element for adjusting the vacuum degree in the sealed cavity. Furthermore, the base station is usually provided with a handle for lifting the base station. Therefore, for the base station in the prior art, if it is necessary to not only meet the function of storing the wiping robot, but also meet the function of fixing the base station to the surface of an object or the ground, and further, it is necessary to provide a handle for lifting the base station, the base station in the prior art needs to be provided with three operating components for user operation, namely, a flip cover, a pressure relief element and a handle, respectively, to realize the three functions. This makes the structure of the base station complicated on the one hand, and on the other hand, the three operating components need to be operated separately to realize the three functions. Therefore, the existing base station is complicated for users to operate, the base station structure is complicated, and the cost is high.
[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Utility Model Content
[0007] One aspect of the technical problem to be solved in this application is how to realize the three functions of storing the wiping robot, fixing the base station to the surface of the object or the ground, and setting a handle for lifting the base station, so that the user operation is simple, the base station structure is simple and the cost is low.
[0008] In addition, other aspects of the present application are also intended to solve or alleviate other technical problems existing in the prior art.

[0018] Optionally, the accommodating cavity has an opening toward the top of the main body, the opening has a first side and a second side adjacent to each other, the cover body can rotate relative to the main body around a first rotation axis, the first rotation axis is consistent with the extension direction of the first side, or the first rotation axis is consistent with the extension direction of the second side.
[0019] Optionally, the receiving cavity has an opening that opens toward the top of the main body, and the cover body can be telescopically deformed to cover the opening or open the opening.
[0020] Optionally, a wire threading hole is provided on the main body, and the wire threading hole is used for allowing a wire harness to pass through, and the wire harness is used to be connected to the wiping robot.
[0021] Optionally, the threading hole is open upward.
[0022] Optionally, the threading hole is a sealed hole that is open toward the receiving cavity and communicates with the receiving cavity, so as to prevent the wiring harness from being exposed to the outside when the wiping robot is received in the receiving cavity.
[0023] According to another aspect of the present application, the present application provides a base station of a wiping robot, which includes:
[0024] a main body, which is provided with a receiving cavity for receiving the wiping robot;
[0025] a mechanical switch, which is disposed in the main body and located outside the receiving cavity;
[0026] a suction cup disposed at the bottom of the main body, the suction cup being provided with a through hole, the suction cup being connected to the mechanical switch, the mechanical switch being configured to close the through hole, thereby forming a sealed cavity that is incompatible with the outside world between the suction cup and the placement surface when the base station is placed on the placement surface, or to open the through hole, thereby opening the sealed cavity through the through hole;
[0027] The cover is arranged on the main body, and the cover can move relative to the main body to close or open the through hole through the mechanical switch, and the cover can close or open the receiving cavity when moving relative to the main body.
[0028] According to another aspect of the present application, the present application provides a wiping robot system, which includes: the base station and the wiping robot mentioned above, wherein the base station is used to be connected to the wiping robot through a safety rope.
[0029] Benefits of this application include:
[0030] 1. The base station of the present application comprises a main body, a cover, a suction cup, and a handle. The cover is movable relative to the main body to close or open a receiving chamber for receiving a wiping robot, thereby realizing the storage function of the wiping robot. The handle is movable relative to the main body and is used to close or open the through hole via a mechanical switch. The handle thus realizes the function of fixing the suction cup to the placement surface and the function of lifting the base station. As such, the base station of the present application does not require an additional button for controlling the mechanical switch on the base station, thus saving the cost incurred by the need for such a button. On the other hand, no additional space is required for the button to be provided on the base station. Since the handle (handle) is already present in the base station, the base station structure is simple and the size is reduced. The user only needs to operate two operating components: the cover and the handle. Since the operating components for fixing the base station and the operating components for lifting the base station are combined into a single operating component handle, compared with the existing method, the present application omits one operating component for the user, thereby simplifying the user's operation. The present application realizes purely mechanical linkage control without the need for a complex structure including a motor or solenoid valve. The control method is stable and reliable, and the base station structure is simple.
[0031] 2. The cover has a first direction for opening the receiving cavity, and the handle moves in a second direction during the process of closing the through hole. The second direction is inconsistent with the first direction, thereby avoiding interference between the operation of the handle and the operation of the cover, which may hinder the function of the handle or the function of the cover. For example, if the first direction and the second direction are both the same rotation direction (rotating to the left), if the user rotates the handle to the left when the cover is in a state of closing the receiving cavity, so that the handle is in a state of closing the through hole, the handle is now arranged outside the left side of the main body. If the cover needs to be opened at this time, the cover needs to be rotated to the left side of the main body, but the left side of the main body is blocked by the handle, so that the cover cannot be rotated to the left side, resulting in the function of the cover being unable to be realized;
[0032] 3. The cover has a first direction for opening the receiving cavity, and the handle moves in a second direction during the process of closing the through-hole. The second direction is inconsistent with the first direction, so as to avoid additional user operations when the second direction is consistent with the first direction. For example, if the first direction and the second direction are both the same rotation direction (rotating to the left), if the user first rotates the cover to the left before turning the handle to the left to close the through-hole, takes out the wiping robot, and then turns the handle to the left to close the through-hole, then when the wiping robot needs to be stored in the receiving cavity after the work is completed, it is necessary to first turn the handle to the right to place the wiping robot into the receiving cavity, and finally turn the cover to the right to close the receiving cavity. Otherwise, the handle will block the cover, and the cover will not be able to rotate to the right, thus making the function of the cover impossible to achieve.
[0033] 4. The through hole on the suction cup can be closed or opened by rotating the cover, thereby realizing the function of fixing the base station. In this way, the cover can realize the fixing function between the suction cup and the placement surface on the one hand, and realize the function of opening and closing the receiving cavity on the other hand. In this way, the base station of the present application does not need to be additionally provided with a button for controlling the mechanical switch on the base station, thereby saving the cost generated by the need for the button, and making the base station structure simple and the volume smaller. The user only needs to operate two operating parts, the cover and the handle. Since the operating part for fixing the base station and the operating part for opening and closing the receiving cavity are combined into one operating part cover, compared with the method in the prior art, the present application omits one operating part for the user, thereby making the user's operation simpler.

[0043] It is easy to understand that, based on the technical solution of this application, without changing the essential spirit of this application, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of this application and should not be regarded as the entire application or as a limitation or restriction of the technical solution of this application.
[0044] The terms "up," "down," "left," "right," "front," "back," "front," "back," "top," and "bottom" mentioned or potentially mentioned in this specification are defined relative to the configurations shown in the accompanying drawings. These are relative concepts and may vary depending on the location or usage of the device. Therefore, these or other directional terms should not be construed as restrictive. Furthermore, the terms "first," "second," "third," and similar expressions are used solely for descriptive and distinguishing purposes and should not be construed as indicating or implying the relative importance of the corresponding components or the order or sequence of their assembly.
[0045] refer to Figure 1 , which shows a schematic structural diagram of a base station 10 proposed according to an embodiment of the present application. Figure 1In order to better illustrate the devices for fixing the base station 10, the main body 800, which may obstruct these devices, has been removed. This does not affect the following description of the relative positions of these devices with respect to the base station 10 or the main body 800. Those skilled in the art will be able to determine the corresponding positions and connection methods of other devices with the main body 800 based on the following description and common configuration methods.
[0046] The base station 10 of the present application is used for a wiping robot 20. The wiping robot 20 may be a window cleaning robot. The window cleaning robot may be used to clean surfaces such as glass surfaces, tile surfaces, and wooden surfaces. The base station 10 of the present application is used to be placed on a placement surface 1. The placement surface 1 may be, for example, the ground. Of course, the placement surface 1 is not limited to the ground, but may also be other physical surfaces, such as a balcony, floor surface, tile surface, etc. in a home, which is not specified in the present application. Further, as Figures 1 to 8 As shown, the base station 10 includes a main body 800, a cover 500, a mechanical switch 100, a suction cup 200, and a handle 300. Here, the main body 800 refers to the portion of the main body 800 excluding the cover 500, mechanical switch 100, suction cup 200, and handle 300 described below. The cover 500, mechanical switch 100, suction cup 200, and handle 300 are all disposed on the main body 800.
[0047] Furthermore, the main body 800 has a top surface, a bottom surface and side surfaces. The top surface is the surface facing upward when the base station 10 is placed on the placement surface 1. The main body 800 can be a rectangular parallelepiped as a whole. However, the main body 800 is not limited to being a rectangular parallelepiped, and can also be other shapes, such as a cylindrical or cubic shape. The main body 800 is provided with a receiving cavity 700 for receiving the wiping robot 20. In this way, the wiping robot 20 can be received through the receiving cavity 700. Specifically, in one embodiment, for example, Figure 3 As shown, the receiving chamber 700 has an opening 17 that opens toward the top of the main body 800. The wiping robot 20 can be placed in the receiving chamber 700 through the opening 17. In another embodiment, for example, Figure 2 As shown, the receiving chamber 700 has a first opening 13 that opens toward the top of the main body 800 and a second opening 15 that opens toward the side of the main body 800. The first opening 13 and the second opening 15 are connected to each other. Thus, the wiping robot 20 can be placed in the receiving chamber 700 through the first opening 13 and / or the second opening 15.
[0048] The cover 500 can move relative to the main body 800 to close or open the receiving chamber 700. In this way, the receiving chamber 700 can be sealed by the cover 500 to prevent the wiping robot 20 housed in the receiving chamber 700 from being exposed to the outside. In one embodiment, the cover 500 is rotatably arranged on the main body 800. For example, Figure 3As shown, the opening 17 has a first side 23 and a second side 25 adjacent to each other. For example, the first side 23 is in the longitudinal direction of the main body 800. The second side 25 is in the width direction of the main body 800. Therefore, the first side 23 and the second side 25 are perpendicular. The cover body 500 can rotate relative to the main body 800 around a first rotation axis. In this embodiment, the first rotation axis is consistent with the extension direction of the second side 25. In other words, the first rotation axis extends along the width direction of the main body 800. Of course, in other embodiments, the first rotation axis is consistent with the extension direction of the first side 23. In other words, the first rotation axis extends along the length direction of the main body 800.
[0049] Furthermore, in another embodiment, the cover 500 is capable of telescopic deformation to cover or open the opening 17. For example, the cover 500 is made of a telescopic material. Thus, when the cover 500 is extended, it covers the opening 17, thereby sealing the receiving cavity 700. When the cover 500 is retracted, it opens the opening 17, thereby opening the receiving cavity 700.
[0050] Furthermore, in another embodiment, the cover 500 includes a first wall 33 and a second wall 35 connected to each other. The first wall 33 is used to seal the first opening 13. The second wall 35 is used to seal the second opening 15. For example, Figure 2 As shown, the first wall 33 and the second wall 35 are perpendicular to each other. When the first wall 33 and the second wall 35 respectively seal the first opening 13 and the second opening 15, the first opening 13 and the second opening 15 can be sealed simultaneously. Alternatively, when the first wall 33 and the second wall 35 respectively open the first opening 13 and the second opening 15, the first opening 13 and the second opening 15 can be opened simultaneously.
[0051] Furthermore, the mechanical switch 100 is located outside the receiving chamber 700 , so as to avoid the mechanical switch 100 occupying the space in the receiving chamber 700 and damaging the wiping robot 20 in the receiving chamber 700 .
[0052] Furthermore, the suction cup 200 is provided at the bottom of the main body 800. Thus, when the base station 10 is placed on the placement surface 1, the base station 10 first presses the suction cup 200 onto the placement surface 1 due to its own gravity. Figure 6 In the embodiment, the suction cup 200 is provided with a through hole 211. Because the mechanical switch 100 can close the through hole 211, when the base station 10 is placed on the placement surface 1, a sealed cavity is formed between the suction cup 200 and the placement surface 1, which is isolated from the outside world. Furthermore, negative pressure is generated within this sealed cavity, allowing the suction cup 200 to adhere to the placement surface 1.
[0053] Furthermore, the mechanical switch 100 can open the through hole 211 so that the sealed cavity is connected to the outside through the through hole 211 , and the suction cup 200 is in contact with the placement surface 1 in an adsorption state, so that the base station 10 can be moved.
[0054] It should be understood that the "sealed chamber" described in the present application includes a vacuum, near-vacuum, or at least a space with a negative pressure less than the standard atmospheric pressure formed between the suction cup 200 and the placement surface 1. Since the space has a negative pressure less than the standard atmospheric pressure, when the space is not connected to the outside world, the atmospheric pressure will press the suction cup 200 onto the placement surface 1 to achieve the effect of adsorption and fixation.
[0055] Furthermore, the handle 300 is movable relative to the main body 800 and is used to close or open the through hole 211 via the mechanical switch 100. Thus, the present application implements the operations of attaching the suction cup 200 to the placement surface 1 and releasing the suction cup 200 from the placement surface 1 via the handle 300. Furthermore, since the handle 300 itself has the function of lifting the base station 10, compared to the prior art, the present application omits an operating component for the user, thereby simplifying the user's operation.
[0056] In one embodiment, the handle 300 is rotatably mounted on the main body 800. Figure 2 As shown, the handle 300 can rotate along the width direction of the main body 800. Of course, the handle 300 is not limited to rotating along the width direction of the main body 800, but can also rotate along the length direction of the main body 800, which is not specified in this application. In another embodiment, as shown in FIG. Figure 4 、 Figure 5 As shown, the handle 300 is slidably disposed on the main body 800 in the up-down direction.
[0057] Furthermore, the cover body 500 has a first direction in which the receiving cavity 700 is opened. Figure 2 As shown, the cover body 500 can be opened outward along the width direction of the main body 800. That is, the first direction is a first rotation direction of opening outward along the width direction of the main body 800.
[0058] Furthermore, when the handle 300 is closing the through hole 211, its movement direction is the second direction. The second direction is inconsistent with the first direction. This avoids the mutual interference between the operation of the handle 300 and the operation of the cover 500, thereby preventing the function of the handle 300 or the function of the cover 500 from being realized. In one embodiment, Figure 2 As shown, the second direction is a second rotation direction along the width direction of the main body 800 and opening toward a side away from the receiving cavity 700. The second rotation direction is opposite to the first rotation direction.
[0059] In another embodiment, Figure 4 、 Figure 5 As shown, the handle 300 is slidably disposed on the main body 800 in an up-down direction. The second direction is a second downward movement direction along the height direction of the main body 800.
[0060] Furthermore, the main body 800 is provided with a threading hole for a wiring harness to pass through, which is used to connect to the wiping robot 20. This allows the wiring harness to connect the wiping robot 20 and the base station 10. If the wiping robot 20 falls, the base station 10 can apply force to the wiping robot 20 to prevent the wiping robot 20 from falling to the ground and causing danger. The wiring harness can be a safety rope, a power cord, or a combination of a safety rope and a power cord.
[0061] In one embodiment, the threading hole is open upward. In another embodiment, the threading hole is a sealed hole that is open toward the receiving chamber 700 and communicates with the receiving chamber 700 to prevent the wiring harness from being exposed when the wiping robot 20 is received in the receiving chamber 700.
[0062] In one embodiment of the present application, the area of the suction cup 200 projected onto the placement surface 1 in the adsorption state is not less than 156.9 square centimeters, so that when the suction cup 200 is adsorbed on the placement surface 1 with a glossiness of not less than 55°, the handle 300 cannot switch the suction cup 200 from the adsorption state to the desorption state under a vertical upward force of not more than 633.7N.
[0063] For the base station 10 of the wiping robot 20, it is used to be adsorbed on the placement surface 1. The placement surface 1 can be the floor inside the house. Of course, the placement surface 1 is not limited to the floor inside the house, but can also be the floor outside the house. Furthermore, the floor inside the house is generally a surface of materials such as tiles, floors, cement, etc. Further, tiles include bright tiles, soft tiles and matte tiles. The glossiness of the bright tiles is greater than 55°, and the glossiness of the soft tiles is greater than 25° and not less than 55°. The glossiness of matte tiles is lower than 15°. In this way, the material differences between the various placement surfaces 1 can be distinguished by glossiness. Further, the suction cup 200 of the present application is adsorbed on a placement surface 1 with a glossiness of not less than 55°. For example, the suction cup 200 of the present application is adsorbed on a soft tile with a glossiness of not less than 55°. Of course, the suction cup 200 of the present application is not limited to being adsorbed on soft light tiles with a glossiness of not less than 55°, but can also be adsorbed on other materials. For example, the suction cup 200 of the present application is adsorbed on a floor with a glossiness of not less than 55°, or the suction cup 200 of the present application is adsorbed on a bright light tile with a glossiness of not less than 55°.
[0064] For the wiping robot 20, the narrow side of the window to be wiped is usually not less than 20 mm, so the outer side length of the square wiping robot 20 generally does not exceed 20 mm at most. Due to this size limitation, the weight of the wiping robot 20 generally does not exceed 2 kg at most.
[0065] When the wiping robot 20 is attached to glass, especially outdoor glass, and is performing wiping work, it may easily fall off the glass if subjected to uncontrollable forces, such as outdoor wind. Since the wiping robot 20 is connected to the base station 10 via a safety rope, after the wiping robot 20 falls off the glass, the base station 10 can promptly apply a dragging force to the wiping robot 20 via the safety rope to prevent the wiping robot 20 from falling to the ground and causing danger. The greater the dragging force that the base station 10 applies to the wiping robot 20 via the safety rope, the more capable the wiping robot 20 is of operating in windier weather. Even if the wiping robot 20 falls due to wind, the base station 10 can immediately drag it through the safety rope to prevent it from falling to the ground.
[0066] If the outdoor wind speed reaches level 4, and the mopping robot 20 falls and is dragged by the safety rope, it could swing outdoors under the influence of the wind. When the mopping robot 20 is dragged by the safety rope and swings outdoors, it will be subjected to centrifugal force and its own gravity. Since the mopping robot 20 is connected to the base station 10 via the safety rope, these centrifugal and gravity forces will ultimately be applied to the base station 10 through the safety rope. In other words, when the safety rope is pulled by the centrifugal force and gravity from the mopping robot 20, the base station 10 will experience an equal amount of tension from the safety rope, and similarly, the safety rope will be pulled by the same force from the base station 10.
[0067] Due to the centrifugal force F = mv 2 / r, so the smaller the swing radius of the wiping robot 20 under the action of wind, the greater the centrifugal force F. Furthermore, the minimum swing radius of the wiping robot 20 under the action of wind is not less than the length of the wiping robot 20 body. Therefore, taking the length of the wiping robot 20 body as the swing radius, under the wind force of level 4 gale (the wind speed of level 4 gale is 5.5-7.9m / s), the maximum centrifugal force to which the wiping robot 20 is subjected when it swings is 2kg*(7.9m / s). 2 / 0.2 = 624.1 N. Gravity G = mg, so the gravitational force G on the wiping robot 20 is 2 kg * 9.8 m / s = 19.6 N. Therefore, the maximum sum of the centrifugal force and gravity on the wiping robot 20 in a force 4 gale is 624.1 + 19.6 = 633.7 N. Therefore, in a force 4 gale, if the wiping robot 20 falls and is dragged by the safety rope and swings, the maximum force exerted by the wiping robot 20 on the base station 10 through the safety rope is 633.7 N.
[0068] Furthermore, when the force applied by the wiping robot 20 to the base station 10 through the safety rope reaches 633.7N under a force of level 4 gale, the base station 10 and the suction cup need to provide a pulling force of 633.7N to the safety rope to ensure that the wiping robot 20 does not fall to the ground. When the base station 10 and the suction cup need to provide a pulling force of 633.7N to the safety rope, if the weight of the base station 10 itself is not considered (ideally), the suction force of the suction cup needs to reach 633.7N. Furthermore, the calculation formula for the suction force of the suction cup is: Suction force = S*P / μ. Where: S is the area of the suction cup 200 (cm 2 ), P is the air pressure (kg / cm 2 ), μ is a safety factor >= 2.5. In this application, S is the area (cm2) of the suction cup 200 projected onto the placement surface 1 in the adsorption state. 2 ), P is 1 atmosphere (1.01x10 5 N / m 2 )1 standard atmospheric pressure = 1.01x10 5 Pa=1.01x10 5 N / m 2 When the suction force of the suction cup needs to reach 633.7N, μ takes the minimum value of 2.5. Then according to the formula S=suction force*μ / P, the minimum S in the ideal state is
[0069] S=633.7N*2.5 / 1.01x10 5 N / m 2 ≈0.015686m 2 ≈156.9cm 2 That is, in an ideal state, the minimum area of the suction cup 200 projected onto the placement surface 1 is 156.9 cm 2 .
[0070] Therefore, when the suction cup 200 of the present application is in the adsorption state and its projected area onto the placement surface 1 is no less than 156.9 square centimeters, and the suction cup 200 is adsorbed on the placement surface 1 with a glossiness of no less than 55°, and the handle 300 is applied with a vertical upward force of no more than 633.7 N, the suction cup 200 cannot be switched from the adsorption state to the de-adsorption state. In other words, even when the wiping robot 20 is subjected to the centrifugal force of a force 4 gale, which in turn causes a significant pulling force (633.7 N) on the base station 10, the base station 10 can still be firmly fixed to the placement surface 1 through the adsorption of the suction cup 200. In other words, the base station 10 can drag the main wiping robot 20 via the safety rope without causing it to fall to the ground. This is because when the suction cup 200 is adsorbed on the placement surface 1 with a glossiness of no less than 55°, the base station 10 can withstand a maximum pulling force of 633.7 N. On the other hand, while the base station 10 can withstand a maximum pulling force of 633.7N, the area of the suction cup 200 can also be kept small, avoiding inconvenience to users due to increasing the footprint of the suction cup 200 to improve the adsorption force, and allowing the base station 10 to maintain a small size and weight.
[0071] Furthermore, since the handle 300 cannot switch the suction cup 200 from the attached state to the detached state under a vertical upward force of no more than 633.7 N, this prevents the user from accidentally operating the handle 300. An adult's pulling force is generally 38 kg, which translates to approximately 380 N. Therefore, with the suction cup 200 attached to the placement surface 1 in this embodiment, the pulling force of an adult cannot pull the base station 10. This prevents the user from accidentally detaching the suction cup 200 by pulling on the handle 300 or the base station 10 itself.
[0072] In one embodiment of the present application, for example, Figure 6 、 Figure 7 In the embodiment of the present invention, the handle 300 is connected to the mechanical switch 100 via a transmission mechanism 400. The transmission mechanism 400 is connected to the mechanical switch 100 via a transmission mechanism 400. Figure 6The figure shows a three-bar linkage, comprising a first link 410, a second link 420, and a third link 430, which are hinged in sequence along the direction of gravity. The end of the first link 410 facing away from the second link 420 is connected to the handle 300, and the end of the third link 430 facing away from the second link 420 is connected to the mechanical switch 100. The transmission mechanism 400 is used to transmit the rotational motion of the handle 300 to the mechanical switch 100, enabling the mechanical switch 100 to close or open the through-hole 211. It should be understood that the transmission mechanism 400 can also be configured as other transmission mechanisms, such as a gear transmission mechanism, a belt transmission mechanism, a chain transmission mechanism, etc. The configuration of the transmission mechanism 400 provides multiple positioning possibilities for the handle 300 on the main body 800, and the transmission mechanism 400 can adjust the motion transmission ratio between the handle 300 and the mechanical switch 100. The input end of the transmission mechanism 400 is connected to the handle 300, and the output end is connected to the mechanical switch 100.
[0073] In one embodiment of the present application, the handle 300 may be directly connected to the mechanical switch 100 without a transmission mechanism, so that the rotational motion of the handle 300 is directly converted into motion of components in the mechanical switch 100. The following embodiments are applicable not only to technical solutions with a transmission mechanism 400, but also to technical solutions without a transmission mechanism 400. This point will not be elaborated upon in the following embodiments.
[0074] In one embodiment of the present application, the mechanical switch 100 includes a first valve element connected to the suction cup 200 and a second valve element connected to the handle 300. An opening 111 is provided on the first valve element, and the opening 111 is connected to the through hole 211. The rotation of the handle 300 drives the second valve element to rotate relative to the first valve element to open and close the opening 111. When the opening 111 is opened, the through hole 211 is connected to the outside world through the opening 111, and the sealed cavity is also connected to the outside world, and the suction cup 200 is detached. When the opening 111 is closed, the through hole 211 and the sealed cavity are both sealed from the outside world, and the suction cup 200 is adsorbed. Figure 8 , which shows a schematic structural diagram of the mechanical switch 100 of this embodiment. Figure 8In this embodiment, the first valve element is a valve body 110, and the second valve element is a valve core 120 at least partially inserted into the valve body 110. The valve core 120 is rotatable relative to the valve body 110. The valve body 110, for example, includes a first valve body section 101 parallel to the placement surface 1 and a second valve body section 102 perpendicular to the placement surface 1. The valve core 120 is inserted into the first valve body section 101, and the valve body 110 is connected to the suction cup 200 via the second valve body section 102. In an embodiment in which a transmission mechanism 400 is provided between the handle 300 and the mechanical switch 100, the end of the third connecting rod 430 of the transmission mechanism 400 facing away from the second connecting rod 420 is connected to the valve core 120. In an embodiment in which no transmission mechanism 400 is provided between the handle 300 and the mechanical switch 100, the handle 300 is directly connected to the valve core 120. It should be understood that in an embodiment not shown, the second valve element may also be configured as a valve body, and the first valve element may be configured as a valve core at least partially inserted into the valve body, the valve core being rotatable relative to the valve body. This configuration may also be correspondingly applied to the following embodiments.
[0075] Furthermore, in one embodiment of the present application, a first channel 112 is provided through the valve body 110, and a second channel 122 is provided on the valve core 120 for communicating with the first channel 112. One end of the second channel 122 is an open end 1221, and the other end is a closed end 1222. In other words, the valve body 110 and the valve core 120 are configured as hollow cylinders, and their hollow chambers are connected to each other. Figure 8 In the embodiment, the valve core 120 is inserted into the valve body 110, for example, through the open end 1221 of the second channel 122, so that the second channel 122 and the first channel 112 are connected, especially sealed relative to the external atmosphere.
[0076] Furthermore, in one embodiment of the present application, in particular Figure 8 In the embodiment, the opening 111 is provided on the side wall of the valve body 110. Specifically, as Figure 8 As shown, a joint is provided at one end of the first valve body section 101 away from the second valve body section 102, through which the valve core 120 is inserted into the first valve body section 101. The opening 111 is provided on the joint. An exhaust port 121 is provided on the side wall of the valve core 120. When the valve core 120 rotates relative to the valve body 110, the exhaust port 121 is connected to or offset from the opening 111 to open or close the opening 111. When the exhaust port 121 is connected to the opening 111, the through hole 211 is connected to the outside atmosphere through the opening 111 and the exhaust port 121. When the exhaust port 121 is offset from the opening 111, the through hole 211 is connected to the enclosed space formed by the first channel 112 and the second channel 122, but is sealed from the outside atmosphere.
[0077] Another aspect of the present application further provides a base station 10 of a wiping robot 20, comprising: a main body 800, which is provided with a receiving cavity 700 for receiving the wiping robot 20; a mechanical switch 100, which is provided in the main body 800, and the mechanical switch 100 is located outside the receiving cavity 700; a suction cup 200, which is provided at the bottom of the main body 800, and the suction cup 200 is provided with a through hole 211, the suction cup 200 is connected to the mechanical switch 100, and the mechanical switch 100 is used to close the through hole 211, thereby making the wiping robot 20 When the base station 10 is placed on the placement surface 1, the suction cup 200 forms a sealed cavity that is not connected to the outside world between the suction cup 200 and the placement surface 1, or the mechanical switch 100 is used to open the through hole 211, and then open the sealed cavity through the through hole 211; the cover body 500 is arranged on the main body 800, and the cover body 500 can move relative to the main body 800 to close or open the through hole 211 through the mechanical switch 100, and the cover body 500 can close or open the accommodating cavity 700 when moving relative to the main body 800.
[0078] Furthermore, when the cover body 500 moves relative to the main body 800 to open the accommodating cavity 700, the through hole 211 can be closed by the mechanical switch 100, thereby realizing the fixing function between the suction cup 200 and the placement surface 1; when the cover body 500 moves relative to the main body 800 to close the accommodating cavity 700, the through hole 211 can be opened by the mechanical switch 100, thereby realizing the fixing release function between the suction cup 200 and the placement surface 1.
[0079] In such Figure 2 In the illustrated embodiment, the cover 500 can be rotated outwardly along the width direction of the main body 800 to open the receiving cavity 700. This not only realizes the fixing function between the suction cup 200 and the placement surface 1, but also realizes the function of opening the receiving cavity 700. As such, the base station 10 of the present application does not need to be provided with an additional button for controlling the mechanical switch 100 on the base station 10, thus saving the cost incurred by the need for such a button, and making the base station 10 simple in structure and compact in size. The user only needs to operate two operating components, namely the cover 500 and the handle. Since the operating components for fixing the base station 10 and the operating components for opening and closing the receiving cavity 700 are combined into one operating component, the cover 500, the present application omits one operating component for the user compared to the prior art, thereby simplifying the user's operation.
[0080] The third aspect of the present application further provides a wiping robot 20 system, comprising: the base station 10 and the wiping robot 20 as described above, wherein the base station 10 is used to be connected to the wiping robot 20 via a safety rope.
[0081] The wiping robot 20 system has all the technical effects of the aforementioned base station 10, which will not be repeated here.
[0082] It should be understood that all the above preferred embodiments are illustrative rather than restrictive, and that various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of this application should be within the legal protection scope of this application.
